Second Factor - Hardware OTP

Designed with security in mind this 100% native application lets you generate OTP codes for all services with TOTP second factor.

This application uses Sandboxing feature, and not requires network access - so it is guaranteed by operating system that your keys or authentication codes will not leak anywhere via network.

* NOTE: You need to have Yubikey device to generate codes. This app does not provide storage for your OTP keys!
* NOTE: Application supports only modern yubikeys with TOTP CCID support (for example Yubikey 4, refer to manufacturer documentation).

Main features of application:
* Fast and stable 100% native application
* TOTP with SHA1, SHA256, SHA 512 (if supported by you hardware)
* Both 6 and 8 digits codes
* PIN
* Sandboxed app - you don't have to trust me. Your keys and codes are protected from leakage by OS
* Adding OTPs from QA codes by drag-drop image files or by scanning screen (although app is able to capture image from screen, it is processed locally and not sent anywhere - it is guaranteed by Sandox function of macOS)

Features not yet supported (planned for future releases):
* Codes protected with hardware button touch
* HOTP codes
* Codes with non-standard period. At this time only codes with 30 seconds period (used by almost all popular services) are supported

Please note: if yours hardware key contains any of not-yet-supported OTPs - they will not be shown in this application.
